Air Quality – What Can Be Done?

We’ve all seen the pictures of extreme air pollution around China. And the UK had its time in the smog, with the Great Smog of 1952 where it was so bad people died.

However, the EPA (US Environmental Protection Agency) conducted a study that showed the air quality in the average home is up to five times dirtier than the air outside. Luckily, there is a pretty easy way for improving the indoor air quality of your home – have clean air ducts. Yes, your house has air ducts, just like all the buildings in those blockbuster action films everyone’s seen, only yours are too small for you to play spy in.


Over time, and especially with use, dust and debris start to build up. But they’re not the only things; mold, insects, and even rodents tend to inhabit these tiny passageways, allowing your central air and heat system to spread their filth around your house like they own the place. Needless to say, this can have a largely negative impact on your health.

By getting your air ducts cleaned and your air conditioning maintained and replaced regularly, say once or twice a year, you can do your part to help ensure that it’s healthier for you to breathe inside instead of outside.
